This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

The boiling point of the alcohol ethanol is 78.29 °C, ... The oxidation of secondary alcohols (R 1 R 2 CH−OH) normally terminates at the ketone (R 1 R 2 C=O) stage.
Hydrogen chloride boils at −85 °C and water at 100 °C, but the azeotrope boils at 110 °C, which is higher than either of its constituents. The maximum boiling point of any hydrochloric acid solution is 110 °C. Other examples: hydrofluoric acid (35.6%) / water, boils at 111.35 °C; nitric acid (68%) / water, boils at 120.2 °C at 1 atm

Like other butanols, butan-2-ol has low acute toxicity. The LD 50 is 4400 mg/kg (rat, oral). [6]Several explosions have been reported [7] [8] [9] during the conventional distillation of 2-butanol, apparently due to the buildup of peroxides with the boiling point higher than that of pure alcohol (and therefore concentrating in the still pot during distillation).
There are two conventions regarding the standard boiling point of water: The normal boiling point is commonly given as 100 °C (212 °F) (actually 99.97 °C (211.9 °F) following the thermodynamic definition of the Celsius scale based on the kelvin) at a pressure of 1 atm (101.325 kPa).
